摘要
The effect of selenium addition on supersaturation observed in aluminium deoxidized molten iron was studied at 1873K, by using Fe-Al alloys and CaO-Al2O3 slags in an alumina crucible. Selenium mass content was varied from 0.0005 to 1.81%. In experiments where the samples were rapidly quenched, the contents of supersaturated oxygen for given aluminium levels were not influenced by the addition of selenium. However, the effect of selenium addition on supersaturation was observed for mass contents of more than 0.009% selenium. The selenium distribution ratio between liquid iron and CaO-Al2O3 slags was determined as a function of the aluminium content of the melt.
